Frequently Asked Questions

How do you solve quadratic word problems?

To solve a quadratic word problem, you must first write down the root of the problem. ;) You know b and c, but not a. Now from the text, you must find out what is the mathematical relation between a, b and c, and write it down as a formula. Then wether the formula is quadratic or not, solve it in the normal way.

What is an example of a quadratic formula?

A quadratic equation is an equation that can be written as ax ² + bx + c where a ≠ 0 In other words, a quadratic equation must have a squared term as its highest power Examples of quadratic equations.

How do you solve a quadratic function?

Solve quadratic function word problems by determining each term of the quadratic equation and then solving for x when the equation is equal to zero. A quadratic equation is expressed as ax^2 + bx + c = 0 when in standard form.

How do you calculate quadratic equations?

The Quadratic Formula: For ax2 + bx + c = 0, the values of x which are the solutions of the equation are given by: For the Quadratic Formula to work, you must have your equation arranged in the form (quadratic) = 0. Also, the 2a in the denominator of the Formula is underneath everything above, not just the square root.
